Before that, the team will have to trim their roster down to 53 players. Earlier in the week, the Broncos released 11 players bringing their roster down to 77.

Still, several more cuts need to be made—24 to be exact. While some of those players will be placed on the team's practice squad, the Broncos still have plenty of decisions looming prior to the first game of the season.

So, who is on the roster bubble and what side of it will they end up on? The front office and coaching staff will be faced with some tough decisions. Here, we will look at the players they will have the toughest time deciding on.

Zac Dysert, Quarterback

Zac Dysert has only in appeared in one preseason game thus far, completing all three of his passes for 16 yards against the 49ers.

Instead, the Broncos have opted to give extended work to Brock Osweiler, allowing him to develop in his second year with the team.

Dysert will likely see plenty of time in the preseason finale on Thursday against the Arizona Cardinals. His performance in that game may determine whether he sticks with the team or not, though he may just be playing for a spot on the practice squad.

The Broncos saw enough in Dysert to use a seventh-round draft pick on him in April, but whether they spend a roster spot on a third quarterback is hard to say—but it doesn't seem likely.

C.J. Anderson, Running Back

C.J. Anderson had 69 yards rushing on 15 carries in his only preseason game, but was injured not long after during practice.

Though the injury doesn't appear to be season-ending, it will keep Anderson on the shelf for awhile. So, what do the Broncos do with the undrafted rookie who looked impressive against San Francisco?

They could keep him on the roster despite the fact that he will be out several weeks—at least—or they could option him to the practice squad. Of course, the third choice would be to release him altogether.

Anderson showed a lot of promise in the limited action he saw. The Broncos running back situation seems a little shaky with Ronnie Hillman's ball security issues and Montee Ball whiffing on blocks during pas-protection.

Because of that, there is a spot on the roster for Anderson, though the practice squad seems more likely.
